CROSS-REFERENCE TO RELATED APPLICATION

The present application relates to, and claims priority to U.S. Provisional Patent Application Ser. No. 62/110,030 filed on Jan. 30, 2015, which is entitled “A Ramp Wedge, with an inside platform that helps role people in wheel chairs in the shower/tub”. The content of this provisional application is incorporated herein in its entirety by reference.

TECHNICAL FIELD OF THE INVENTION

This invention relates broadly to the art of bathroom facilities, and more specifically to bathroom facilities such as tubs and showers which can be used by handicapped persons in wheelchairs, walkers, and other mobility devices without the need to permanently change or make costly repairs to the bathroom.

BACKGROUND OF THE INVENTION

In recent years, emphasis has been placed on making bathroom facilities accessible to handicapped persons, including persons in wheelchairs. However, most homes, hotel rooms, apartments, and the like are constructed for non-handicapped people, for both cost-cutting and aesthetic reasons, unless such buildings are specifically constructed with handicapped persons in mind. Normally, even when homes are constructed with handicapped persons in mind, tubs and showers are merely provided with grab bars, which is inadequate for many situations. Many individuals have difficulty stepping into the bathtub, lowering themselves for a bath, and then getting out of the tub following the bathing procedure. Often these individuals must resort to having bed baths, sponge baths, or entirely change their current bathroom to accommodate a roll in shower.

Furthermore, it often occurs that a person unexpectedly becomes seriously handicapped while living in a house or apartment which was not constructed, or inadequately constructed to accommodate seriously handicapped persons. This happens, for example, when a person sustains a debilitating injury, becomes old, is struck with illness, or the like. When this occurs, it is often quite difficult and expensive to radically modify a home to include bathroom facilities for accommodating the newly handicapped person. Indeed, new installations that require the demolition and removal of existing showers or bathtubs are expensive, labor intensive and environmentally unfriendly. Additionally, the replacement, ‘handicap accessible’ types of bathtubs or showers (such as roll in showers or the like) are often very expensive and complex to operate.

Thus, it is an object and advantage of this invention to provide a handicap-accessible bathroom including shower and or tub which requires little to no installation of parts or demolition of existing structures. Advantageously, the present invention allows a handicapped person to continue to use their existing bathroom facilities without resorting to expensive and time-consuming repairs.

Often, it is desirable to construct a handicap-accessible bath tub or shower in a building on a temporary basis and remove it later. Such a need arises when a person is either terminally ill or temporarily ill, both of which happen fairly often. Thus, it is an object of this invention to provide a kit which can be used in conjunction with a standard bath tub and/or shower when a person becomes handicapped which can also be relatively easily and inexpensively removed when it is no longer necessary to have this kind of set up. The present invention allows the system to be removed and set up several times a day with minimal effort.

Furthermore, there are no devices on the market that are relatively lightweight and easily foldable or storable, such that after each use, the handicapped user may independently store the device away to allow free access to the bathtub or shower by other non-handicapped individuals.

It is also an object of this invention to provide such a handicap-accessible bathtub and/or shower which is durable and convenient for a handicapped person in a wheelchair to use, but yet which is relatively inexpensive and easy to install or requires no installation whatsoever.

The present invention overcomes all the aforementioned problems by providing a simple kit including a ramp and an insert for any shower or bathtub that can be purchased and set up for use in conjunction with any existing bathroom arrangement.

DETAILED DESCRIPTION

The invention provides a method and kit for allowing a handicapped user to use a standard bathtub and/or shower by providing a ramp and bathtub or shower insert which is uniquely designed to fit within any standard bathtub or shower. Such a system requires little to no installation and may be made portable and lightweight for storage and/or travel. The present invention works with any type of bathing enclosures, bathtub, or shower.

The preferred embodiment of the ramp and insert kit and system 10 is shown in FIGS. 1 through 7, 10 a and 10 b. Referring to FIGS. 1 and 2, ramp 11 is provided having a high end 12, a low end 13, a top surface 14 and generally triangular sidewalls 15 and 16. Preferably, the top surface 14 includes ridges 17 as shown in FIG. 1 in order to provide the traction necessary to aid a user in safely rolling or walking down the ramp on an incline. Any type of non-stick coating or slip resistant surface is considered to be within the scope of this invention. For example, slip resistant tape or traction tape may be applied at various points along the top surface 14 of the ramp. The slip resistant or traction tape may take on a variety of shapes, such as strips, circles, squares or the like. The tape or traction may also cover the entire portion of the top surface 14. The height of the high end 12 is designed to be flush (at the same height) with the surface of a shower ledge or bathtub ledge, as will be shown in later figures.

FIG. 3 illustrates the wheelchair 30 being used in conjunction with insert 20, which has been adapted to fit within a standard sized bathtub, 40. FIG. 3 shows the insert in a slightly lifted formation in order to show the components of the insert, however, the insert is preferably designed to sit inside the bathtub 40, such that feet 31 and 32 are in contact with the floor 41 of the bathtub 40. This arrangement ensures a stable surface on which a handicapped individual can roll on in order to perform his bathing needs. The insert 30 preferably includes drain holes 34 a, 34 b and 34 c which are formed in between the slats 33 a, 33 b and 33 c of the insert, for example. The drain holes are important in allowing water to drain through the structure of the insert and into the drain of the bathtub and prevent water from flowing out of the bathtub.

The drain holes are formed in FIG. 3 as spaces between slats 33 a, 33 b and 33 c, etc., as result of the slat design of the insert. However, it is envisioned that the drain holes could be placed anywhere along the surface of the insert 20, and could take on a variety of different shapes, such as circles or long rectangular elements along the perimeter of the insert, for example.

In another embodiment, the insert may be constructed of a solid piece of material which is not composed of slats. The top surface 21 of the insert may be a completely flat surface, or in the case of a solid insert with no slats, the top surface may take on a slightly convex or concave shape in order to encourage drainage or collection of water in particular areas. For example, the insert may be convex in cross sectional shape with drain holes located on the outside perimeter of the insert. This shape may also encourage stability of the wheelchair. In another example, the insert may be slightly concave in cross sectional shape with one or more drain holes placed in the center of the insert to encourage drainage in the center of the insert and keep water away from the perimeter.

In one embodiment, the top surface of the insert may include indentation or grooves designed to accommodate or lock in place the wheels of a wheel chair in order to secure the wheelchair and keep it from slipping off the surface while in the bathing or showering position. Other details could be added to the surface of the insert to encourage precise positioning of the wheelchair and discourage movement of the wheelchair during the bathing or showering process. It is envisioned that for the safety of the user, the wheelchair or other mobility device should be left in a locked position while bathing.

The bathtub 40 includes a top surface having a top ledge 35 around the perimeter of the tub. The design of bathtub 40 is merely provided in FIG. 3 for explanatory purposes. However, it is envisioned that the present invention could be fixed onto or work with any standard or non-standard tub configuration. The bathtub 40 includes two long outside walls 36 a and 36 b, and two short outside walls, 36 c and 36 d. The bathtub also includes two long inside walls 37 a and 37 b, and two short inside walls 37 c and 37 d. Each of walls of the bathtub 36 a, 36 b, 36 c, 36 d, 37 a, 37 b, 37 c, and 37 d are shown in cross sectional views 10 a and 10 b. The insert is designed to fit snugly within the hollow space 39 of the bathtub, such that the two longer sides of the insert substantially touch the inside side walls 37 a and 37 b, respectively, and the shorter sides of the insert substantially touch inside side walls 37 c and 37 d, respectively. In a preferred embodiment, the insert top surface covers the entire open space of the tub such that there are no areas where the wheelchair could roll and/or fall through.

In a most preferred embodiment, the top surface 21 of the insert 20 is positioned at a height such that it is flush with the top surface of top ledge 35 of the bathtub. The inner floor 41 of the bathtub is in connection with feet 31 and 32 of the insert 20. The inner floor may take on a substantially rectangular or substantially oval shape, depending on the design of the bathtub. FIG. 11a shows the shape of the inner floor 41 of the bathtub 40, with sidewalls curving in an upwards direction along the perimeter of the floor, as is the conventional shape of a bathtub.

The height of the feet 31 and 32 of the insert should be substantially the same and is designed such that they can hold up the top surface 21 of the insert to be approximately flush with the top surface of the top ledge 35. This will ensure easy entry from the ramp to the insert using a wheelchair, walker or other type of device to aid in the movement of a handicapped person. For example the feet 31 and 32 are shown in FIG. 5 as two rectangular pieces of plywood having a height of approximately 6 inches. Any type of material may be used to make up the feet 31 and 32 and the material can be made larger or smaller depending on the height of the bathtub or shower the insert will be placed into. A height of about 2-10 inches is preferable in the case of a shower stall application, whereas a height of about 10-36 inches is preferably in the case of a bathtub application.

FIG. 5 shows the underside of the insert with two longer sides 51 a and 51 b, and two shorter sides 51 c and 51 d. The insert 20 is being used in a standard shower stall 60. As with the bathtub application, the size of the insert 20 corresponds closely to the inner floor 53 of the shower stall. Therefore, the shape of the insert is dependent on the shape of the shower stall, whether it be square, rectangular, or a non-standard geometric shape. Such shapes can be achieved by cutting the insert using precise measurements of the floor of the shower. FIG. 11b depicts an example of a substantially square shape of the shower floor 53.

FIGS. 12a and 12b provide a cross sectional view of the shower stall 60, which includes two long outside walls 66 a and 66 b, and two short outside walls, 66 c and 66 d. The shower also includes two long inside walls 67 a and 67 b, and two short inside walls 67 c and 67 d. Each of walls of the bathtub 66 a, 66 b, 66 c, 66 d, 67 a, 67 b, 67 c, and 67 d are shown in cross sectional views 12 a and 12 b. The portion of the shower between inside side wall 67 a and outside side wall 66 a make up the ledge 61 of the shower. The insert is designed to fit snugly within the hollow space 52 of the shower stall, such that the two longer sides of the insert substantially touch the inside side walls 67 a and 67 b, respectively, and the shorter sides of the insert substantially touch inside side walls 67 c and 67 d, respectively. In a preferred embodiment, the insert top surface covers the entire open space of the shower such that there are no areas where the wheelchair could roll and/or fall through.

A partial view of the ledge 61 of the shower stall 60 is shown in FIG. 5. Slats 33 a, b and c and the openings for drainage 34 a, b and c are shown in more specificity in FIG. 5. The width of the slats may be about 1 inch to about 12 inches each, depending on durability and aesthetic appearance desired. In another embodiment, the insert may be formed out of a solid piece of material instead of slats with drainage holes placed thereon, as discussed above with respect to the bathtub application.

To construct the insert, two or more slats of a suitable dimension are created, being of a substantially rectangular shape. Two or more feet are then sized according to the dimensions of the inner floor space of the bathtub 41 or the inner floor space of the shower designated as 53. In inner floor space of the bathtub and shower is shown in FIGS. 11a and 11b . The feet are attached to the slats by suitable method, such as screws, nails, or strong waterproof adhesive, for example. Preferably, nails are used to attach each rectangular slat to the feet 31 and 32. The slats may be spaced adjacent to each other such that a sufficient opening is made between each slat for water to drain. For example, the space between each slat may be between 1 mm and 3 inches, for example.

Both the ramp 11 and the insert 20 may be made of any water proof material with the strength required to support users of the ramp and insert system 10. Preferably, the ramp and insert are formed from a high-density, marine grade of polyethylene, and is approximately between 0.25 and 4 inches in thickness. When made of the preferred polyethylene material, the ramp and insert are durable, highly impact resistant, mildew resistant and machine-able. When made from the preferred polyethylene, the ramp and insert can be heated in an oven to render the material flexible, and then bent along the break-line, to form the angles in the material as needed according to the figures shown.

Other conventional materials could be employed for use in fabricating the ramp and insert, and the two components do not need to be constructed of the same material. For example, the ramp could be constructed of marine grade plywood, and the insert could be constructed of a marine grade plastic. Other materials which could make up the ramp and insert components include wood including marine grade plywood, metals and metal composites such as stainless steel, high-strength aluminum, high strength foam materials, or other forms of hard durable plastic. Considerations in choosing the right material include the weight of the material, its durability and load bearing strength, as well as waterproofing characteristics including an anti-rust and an anti-corroding material.

Preferably, the material may be lacquered, painted, or otherwise be made to have additional coatings placed thereon to extend the life, moisture retention, durability and aesthetic appearance of the material.

In particular, the insert 20 should be constructed of a material which is able to support a large load as the insert must be capable of supporting an individual and his wheelchair and perhaps even one or more additional individuals to aid in the bathing or showering process. Preferably, the material can withstand a load of between 300 and 1,000 lbs, preferably between 350 and 700 lbs and most preferably between 400 and 600 lbs.

The underside of the ramp 11 is shown in FIG. 6, which illustrates the structure of the ramp including generally triangular sidewalls 15 and 16, middle support 70 and cross beams 71 a, b, c, d, e and f. It is envisioned that a variety of ramp designs may be used in conjunction with this ramp and insert kit, with the important features of the ramp being its ability to withstand heavy load, up to 700 lbs, for example, traction to prevent slipping, waterproofing, and the ability of the ramp to be stored away easily.

The kit and system 10 of the present invention is depicted in FIGS. 4 and 7 being used in conjunction with a standard shower stall 60. In practice a user who wishes to take a shower would roll his or her wheelchair up the ramp 11, past ledge 61 and onto insert 40. Once on top of the insert, the weight of his body and his wheelchair are supported by the design and material of the insert, discussed above. The wheelchair may then be placed in the locked position such that the wheels cannot move. Alternatively, the user can wheel himself into one or more indentations or grooves meant to hold the wheels of the wheelchair in place while on top of the insert 20. One particular advantage of the insert is that the user is able to stay in an elevated position from the shower floor due to the feet of the insert and is therefore better able to reach the shower controls which are sometimes placed in unreachable areas for those sitting down. Once the water control is turned on, the water easily drains through the spaces formed between slats 33 a, 33 b and 33 c of the insert and thereafter down through a standard shower drain.

FIG. 7 depicts the precise configuration of the insert and the ramp relative to the ledge 61. It should be understood that the same procedure may be used in conjunction with a bathtub 40 with the ramp 11 and insert 20 being configured to be flush with ledge 35. In this way, a handicapped user using a mobility device is able to easily use his existing bathtub or shower arrangement by the simple addition of two removable components to his bathroom, ramp 11 and insert 20. The ramp and insert are preferably provided in a kit form. In practice, the user may provide certain dimensions of their tub or shower before construction. Alternatively, a representative may visit the home of the handicapped individual to obtain precise measurements. In another embodiment, a number of standard sized ramps and inserts may be prefabricated according to the above-described steps to ensure quick turn-around of ordering by users seeking to purchase the kit. The prefabricated inserts and ramps may be made to fit with a number of different standard sized bathtubs and showers. In one embodiment, the brand and model of the bathtub or shower may be provided by the user with the manufacturer having the dimensions of the same in his database.

The ramp 11 and insert 20 may be packaged in a single package or several separate packages and may be partially assembled or completely assembled for the convenience of the customer. Alternatively, the ramp 11 and insert 20 may be provided in one or more packages in a completely disassembled state in order to efficiently pack and ship the kit. The ramp and insert kit may also be delivered and/or assembled by a representative to ensure an exact fit with the existing tub or shower of the user.

In an alternative embodiment of the invention, an insert 80 is provided in FIG. 8, which is capable of being folded and stored away by the user. This insert may be mounted anywhere on the surface of the bathtub 40 or shower stall 60, including any bathroom walls, such as through use of a hinge system or other mechanical fastening system, for example.

In an alternative embodiment of the invention, an insert 90 is provided in FIG. 9, which is capable of being rolled in place and over the hollow space of the bathtub or shower. This insert may be mounted anywhere on the surface of the bathtub 40 or shower stall 60, including any bathroom walls, such as through use of a hinge system or other mechanical fastening system, for example.

While several particular forms of the invention have been illustrated and described, it will be apparent that various modifications and combinations of the invention detailed in the text and drawings can be made without departing from the spirit and scope of the invention. For example, references to materials of construction, methods of construction, specific dimensions, shapes, utilities or applications are also not intended to be limiting in any manner and other materials and dimensions could be substituted and remain within the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
